This device is specifically engineered to provide optimal transient overvoltage and surge protection for medium voltage DC systems up to 150VDC. It is widely used in industrial automation, solar photovoltaic systems, telecommunications, and wind power setups.
The high-visibility orange housing is designed for quick identification and easy maintenance. It allows technicians to instantly locate the surge protective device inside crowded electrical panels and distribution boards.
The 40kA rating (8/20µs wave) represents the maximum amount of surge current the device can safely divert to the ground during a single transient event, such as an indirect lightning strike, ensuring robust protection for downstream equipment.
The integrated visual indicator provides real-time status monitoring. When the device is operating normally, the indicator shows a clear status; if the internal protection components degrade due to surge events, the indicator changes color, signaling that the module needs replacement.
The device features a standard DIN rail mounting system (35mm), allowing it to be easily and securely installed in standard control cabinets, distribution boxes, and switchboards without requiring specialized tools.
